Humayun’s tomb is located on Mathura road, Nizamuddin East, New Delhi, India.
The tomb is of the Mughal Emperor Humayun and was ordered by Humayun’s first wife Empress Bega Begum, in 1569-70, who chose a Persian architect to design the grounds. The tomb was declared a UNESCO World Heritage Site in 1993. If you’re an Indian National tickets cost around Rs30, but if you’re a foreigner tickets are Rs500. The upside of paying more is that you’ll most likely get a shorter line, if you hold a foreign passport.
Besides Humayun’s Tomb are several smaller tombs and monuments on the grounds.
It took about an hour to see everything. I recommend going around sunset. The view of the sunset from the top of the tomb is breathtaking.
